Systems and methods for storage operation processing during data migration using selective block migrated notifications are disclosed. A host system may be configured with connections to a source storage node and a destination storage node while a data migration is moving data blocks from the source to the destination. The host may send a storage request to the source storage node and receive a block migrated notification from the source storage node. The host may then store a migrated indicator for that data block in a migration table and direct future storage requests to the destination storage node.
